Thread: Anyone know the difference between rotor head designs?

Is the trick where a bolt goes through the rotor head and seats against the dizzy shaft pictured?

Don't worry about it. It's a high port external coil distributor trick.

You have a low port internal coil distributor where the rotor snap on.

I have no idea why Kyle brought up the high port distributor, only leads to more confusion.

Btw, the new factory rotors look like the first pic. I got the new rotor and it's the same as the first pic.

It was brought up for the exact purpose of explaining any possible confusion. Real simple. His signature shows a 96 G20 and 91 B13. He could have both for all I know. I don't know anymore information than what was given in the original post.

That coupled with the three Nissan OEM part numbers the OP listed in post #3

To add to the confusion, the '96 B14 lists 2 different part numbers for the rotor, and they are not the same. The '95 uses a different one, and I'm guessing the early '96 does too, while the later '96 -'99 uses a different one. The first time I had to order one many moons ago from Nissan, I ordered the first part number. The triangle inside was smaller than the shaft inside the distributor and would not work. The build date on my car is 8/96.
